need to add new key/value pair in existing dictionary.

I beleive there should be the way of doing it with declarative style something like

     new_data = [x['new_key']=1 for x in simplejson.loads(data)]

(gives syntax error)

how to do something similar ?

EDIT: I need not to merge, but edit existed dict or create or duplicate

`existing_dict['new_key'] = 'new_value'`? If you have a *list* of dictionaries, you can simply loop on them and add for each.. – Maroun Sep 03 '15 at 12:47
of course, but, maybe something more pythonic (laconic) and elegant way exists? – Ilja Sep 03 '15 at 12:49
Why are you doing this in a list comprehension?! – jonrsharpe Sep 03 '15 at 12:49
Are you trying to add the same (key,value) pair to each dictionary in a *list* of dictionaries? – John Coleman Sep 03 '15 at 12:50
just for typing speed purpose – Ilja Sep 03 '15 at 12:50
@Anonymous well that doesn't seem to have sped you up much, now does it? – jonrsharpe Sep 03 '15 at 12:53
